GATE SECURING AND CLOSING MEANS.

,.App1ication fiIedMay 14, 1325. Serial No. 30,344.

To all coho-m it may concern:

' Be it known that I, Fnnnnnroii J. LYNCH,

eitizen of the Dominion of Canada, residing at NewvlVestminster, in theProvince of British Columbia, Canada, have invented certaindnew anduseful Improvements in Gate Securingand GlosingMeans, of which thefollowing is a specification.

This invention relates to a means for rapidly closing and securing adoor or gate at iording entrance and exit to a building or the like, thesame being operable by electric means from any part of the building.

It is particularly applicable to a door of that class wherein a seriesof lattice levers pivotally connect a series of uprights, so as to beslidably extensible across a doorway from one or both sides thereof, theinner upright being secured to one of the sides of the doorway and theouter upright hung from a sheave movable on a rail extending across theupper or transom rail of the doorway.

The invention is particularly described in the following specification,reference being made to the drawings by which it is accompanied, inwhich:

Fig. 1 shows he door in the open position closing the doorway.

Fig. 2 is a view of the same when the door is withdrawn to open thedoorway, and

Fig. 3 is an enlarged detail of the electric release mechanism.

In these drawings 2 represents the'doorway to be closed, 3 one of theside posts and l the transom rail of the doorway. The gate by which thedoorway 2 is closed consists of an upright 5 secured to one of the sideposts 3, and 6 is the outer upright of the gate which is suspended at 7from a track rail 8 secured to the transom rail 4 and extending over thedoorway 2.

The inner and outer uprights 5 and 6 are I connected together by anupper and lower series of lattice levers 10 pivotally connected at 11 toone another, and at 12 to a series of uprights 13, so that the gate maybe extended from the fixed upright 5 to close the doorway, as shown inFig. 1, the suspension 7 of the outer upright 6 travelling along thetrack rail 8.

Extension of the gate from the position shown in Fig. 2 to close thedoorway, as shown in Fig. 1, is effected by a bar 15, one end of whichis pivotally connected at 16 to the outer upright 6 of the gate and theother end at 17 to a weight 18, which is vertically movable within acasing 19 formingthe side 3 of the doorway.

.The casing 19 has a slot 20 to permit the bar 15"to be connected to theweight 18 and to move down with it to the horizontal position. Thelength of" the bar 15 is such that when in the horizontal position, thegate is extended to its full limit to closethe door space and a stop isprovided in the easing to check movement of the weight when the bar isin the horizontal position.

At the upper limit of its movement the weight 18 is sustained in thecasing 19 by a latch 21, the end of which is connected by a link 23 tothe end 24 of a lever 25 pivoted at 26 to the side wall of the doorway.The free end of this lever 25 is adjacent the pole of an electromagnet27 in a normally open electric circuit 28 energized by a battery or byconnection to other source of electrical energy. This circuit isclosable at a contact 29 at a convenient place in the buildmg.

On the link is secured a projection 30 which engages an angledprojection 31 from the wall of the casing 19.

When the circuit 28 is closed and the clectromagnet 27 energized, thefree end of the lever 25 is drawn up into contact with the pole of theelectromagnet and the link 23, connected to the other end of the lever25, is drawn down and by engagement of 30 with the incline 31, the upperend of 23 and the latch 21 connected to it are drawn outward anddisengaged from the weight 18. The weight then falls and in fallingprojects the bar 15 from the inclined upright position shown in Fig. 2to the horizontally extended position, as shown in Fig. 1. The weight 18is retained at its lower position by the latch 32 of a lock Theessential features of the invention are the horizontally extensible bar15 connected between the outer end of an extensible gate 6, and a latchsupported weight 18; and the means for withdrawing the latch 21 andpermitting the weight to fall to extend and secure the gate to close thedorway 2. The electric circuit 28 is such that the latch may he releasedfrom any position in the building so that in the event of anyrequirementfor closing the gate, as for instance, the pres ence ofbandits, the gate may be closed and escape prevented.

Having now particularly described my invention, I hereby declare thatwhat I claim as new and desire to be protected in by Lettors Patent, is:

1. Means for shutting and securing a sliding gate to close a doorway,said means comprising the combination with the gate, of a weightvertically movable within a casing on one side of the doorway, a barpivotally con: nected at one end to the weight and at the other endtothe outer style of the gate, a latch sustaining the weight at the upperlimit of its movement and the gate open, and means for withdrawing thelatch and permitting the weight to fall whereby the gate is extendedacross the opening.

, 2. Means for extending a sliding gate to close a doorway and forsecuring it in the closed position, said meanscomprising the.combination with the slidable gate, of a cas ing on the side of thedoorway from which the gate is extended, a weight Vertically movable inthe casing, a bar pivotally connected at one end to the weight and atthe other to the outer style of the gate, a latch retaining the weightat the upper limit of its movement in the casing, means for withdrawingthe latch and permitting the weight to fall, whereby the gate isextended across the doorway, and means for retaining the weight at thelower limit of its movement with the gate shut.

In testimony whereof I al'lix my signature.

FREDERICK J. LYNCH.
